DETERMINATION OF ASCORBIC ACID AS AN INDICATOR TO STRESS AMONG THE PLANTS ALONG MITHI RIVER, MUMBAIRUSHIKESH S. MORE AND SAKSHI S. CHAUBAL
In the present research, the study deals with the determination of ascorbic content in the leaves of plants and analyze its role of ascorbic acid in plants during stress like conditions. Ascorbic acid contents in leaves of Avecinia marina, Ricinuscommunis, Alternantheraparenchyoides, Salvadorapersica, and Peltoptherainnermae were studied for their ascorbic acid content at five different sites each with its ecological importance and geographical diversity. Ascorbic acid, an antioxidant in plants besides being most abundant water soluble antioxidant in plants serves as a major redox buffer and regulates various physiological processes controlling growth and also stress tolerance.It also plays an important role in activation of many physiological and defense mechanism. The intensity of ascorbic acid in plants acts as an indicator of its tolerance against the adverse effects of oxidizing pollutants (Sharma et al., 2016). Present results indicated that the plants at KapadiaNagar showed higher amount of ascorbic acid content compared to other sites. Salvadorapersica of family (Salvadoraceae), common name (Miswak) showed maximum ascorbic acid content at all the sites, and was highest at Kapadianagar Salvadorapersica (8.88 mg/g), It was followed by Peltoptherainnermae (6.74mg/g) and Ricinuscommunis (6.63 mg/g) While the lowest value was recorded at Shashtri Nagar in Peltoptherainnermae (3.19 mg/g) this shows that Salvadorapersica exhibits maximum resistance to stress and exhibits a good tolerance against the adverse effects of oxidizing pollutants.
